Title: Washing machine having weight sensing sensor
Inventor: SEO SOON-CHOL
IPC: D06F33/00
Filed: 1992-09-29
Granted: 1997-12-05
Abstract: A weight sensor(10) is installed close to the bottom of the water tank(6) of an automatic washer. When the washer is not in operation, an elastic spring(12) connected to the rod of the weight sensor(10) contacts the water tank to measure the wash load. As the wash load increases, the water tank lowers and then the rod(14) lowers since the elastic spring(12) is pressed. When the wash load reaches the weight setting, the washer automatically starts to operate. In addition, the circular rotary gear(22) rotates to sufficiently separate the housing(16), in which the rod(14) is inserted, from the water tank(6) so that the weight sensor(10) is protected from the vibration of the water tank(6) due to high-speed spinning of the washer tub(8). Items(26) is a guide to support and fix the water tank(6) when it is moved.

Filed: 1992-04-02
Granted: 1999-11-15
Abstract: Actuating mechanism (1) for a drum brake having provision for operating the brake in either a service brake mode or a park brake mode. The mechanism (1) includes a piston-cylinder assembly (9) which is located between two abutments (13, 15) at respective opposite ends (5, 6) of the brake shoe (3) and which is operable to spread those ends apart to apply the brake in the service mode of operation. The mechanism (1) also includes a pivotally mounted lever (19) which is rotated in one direction during the park brake mode of operation and in so doing coacts with one of the shoe abutments (15) and simultaneously pushes the piston-cylinder assembly(9) against the other abutment (13). The assembly (9) therefore functions as part of the lever (19) for the purpose of spreading the shoe ends (5, 6) and applying the brake in the park brake mode.
